Not too sure what you mean / what your issue is, but you do your bond in the usual /normal way as with any other area of / on your system....just a matter of deciding/finding which material works best for you in terms of tape/s and /or Glue/s ....... there`s nothing ` special` required for a particular area of a system....... are you wearing a topper with flaps or are you wearing 2 temple-partial pieces? If it`s two partials, you`d probably be best to use one of the stronger glues --2 or 3 layers will give the lace [I assume it`s lace] a better ` foundation` to bed-down into. Always ensure each layer has gone practically dry before applying the next layer and it`s VITAL to allow the last layer in particular to do so, before sitting the lace down onto it, otherwise the glue will go through onto the base of the hairs and solidify, and you`ll have a really bad/tough clean-up when you next de-bond. Cheers.
